Description

  The present invention relates to an apparatus for discharging residual contents of an aerosol container for discharging the entire amount of residual contents when the aerosol product is discarded.

  Conventionally, when an aerosol product is discarded after the contents filled in the aerosol container are used, if the contents are left in the aerosol container, it may cause a problem such as an explosion accident due to expansion of the injection gas. was there. Therefore, as shown in Patent Document 1, a residual content discharging apparatus for discharging the entire content remaining in the aerosol container has been proposed.

JP 2006-27718 A

  The residual content discharging apparatus described in Patent Document 1 is formed by inserting and arranging a push button inside a one-touch cap, and a pair of folded pieces project in the direction of the outer peripheral lower end axis of the push button. When the aerosol contents are normally ejected, the push button is mounted on the one-touch cap without folding the pair of folded pieces, and the contents can be ejected to the outside by pressing the top surface of the push button in the stem direction. Further, when discharging the residual contents, the pair of folded pieces are folded back and the push button is attached to the one-touch cap, and the tip of the folded piece is formed on the lower end surface and the inner surface of the inner peripheral wall of the one-touch cap when the push button is pressed. Engage with the engaging part. Then, by engaging the folded piece with the lower end of the inner peripheral wall or the engaging portion, the upward movement of the push button is suppressed and the push button is maintained in the stem direction, and the residual contents can be continuously discharged. .

    However, in the device shown in Patent Document 1, when the entire amount of residual content is discharged, if the push button attached to the one-touch cap is accidentally pushed too deeply into the stem direction, the tip of the folded piece will become the lower end of the inner peripheral wall or the engaging portion. The push button may not be pressed, and the remaining content may not be discharged completely.

  Further, in order to maintain the folded state of the folded piece, it is necessary to provide the engaging portion for engaging the tip of the folded piece on the lower end surface and the inner surface of the inner peripheral wall of the one-touch cap as described above. However, the one-touch cap of the aerosol device is small and requires a high degree of work accuracy to form the engaging portion on the thin inner peripheral wall, and the product itself may be expensive.

    In addition, since the engaging portion provided on such a thin inner peripheral wall is inevitably small, the engaging portion is engaged so that the tip of the folded piece is hooked on the small engaging portion or the thin inner peripheral wall lower end. In this state, it is necessary to maintain the folded state of the folded piece. Therefore, when the aerosol container is vibrated or impacted when the entire amount of the residual content is discharged, the engagement between the folded piece and the engaging portion is easily released, and the folded piece elastically returns to the non-folded state, There is a risk that the discharge of the entire remaining content will be interrupted.

  Accordingly, the present invention is intended to solve the above-described problems, and is intended to obtain an inexpensive product that can discharge the remaining contents reliably and that is easy to manufacture.

    The present invention is intended to solve the above-described problems, and includes a one-touch cap in which an inner peripheral wall is formed on the inner side of the outer peripheral wall via an upper wall, and an aerosol container that is inserted and arranged in the inner peripheral wall of the one-touch cap. And a push button having a lower end connected to the stem. In addition, the one-touch cap has a slit with the upper end at the top from the lower end of the inner peripheral wall toward the upper wall.

    A folded piece that can be inserted into the slit by folding outward is formed by providing cuts on both sides of the push button. In this way, by forming the folded piece by providing the cut on the push button, the folded piece can be formed more easily than in the case of the conventional technique in which the folded piece protrudes from the lower end of the push button.

    In addition, in the state where the folded piece is inserted into the slit, the formation length of the insertion portion is larger than the interval between the inner peripheral wall and the outer peripheral wall so that the outer end portion is disposed upward and abuts against the inner surface of the outer peripheral wall. It should be long. By forming in this way, it becomes possible to suppress the tip of the folded piece inserted by being folded back into the slit and hit the inner surface of the outer peripheral wall at the upper side, and the folded piece can be prevented from elastically returning to the non-folded state, The folded state of the folded piece can be maintained.

    Further, when the aerosol content is normally ejected, the aerosol content can be ejected by attaching the push button to the one-touch cap without folding the folded piece and pressing the push button in the stem direction.

    Further, when discharging the residual contents, the one-touch cap is removed from the aerosol container together with the push button, the push button in the one-touch cap is extracted, and the folded piece is folded upward by more than 90 degrees with respect to the axial direction of the push button. Then, in a state where the folded piece that is folded is inserted into the slit and protruded at the arrangement interval between the inner peripheral wall and the outer peripheral wall, the push button is mounted again on the one-touch cap, and the lower end of the one-touch cap is connected and fixed to the aerosol container. In this way, by attaching the push button to the one-touch cap with the folded piece folded back, as described above, the tip of the folded folded piece hits the inner surface of the outer peripheral wall, and the folded state of the folded piece can be maintained. . In addition, by connecting and fixing the one-touch cap to the aerosol container, the top of the slit of the inner peripheral wall hits the outer surface of the folded piece, and this top presses the push button through the folded piece, and the push button is pressed. It is possible to maintain and discharge the residual contents continuously.

  In addition, the one-touch cap may be provided with a lower end protrusion that can abut the lower end edge of the push button at the lower end of the inner surface of the inner peripheral wall. By forming in this way, the push button incorporated in the one-touch cap engages with the lower end protrusion during storage, transportation, assembly work, etc. before assembling to the aerosol container. It is possible to prevent separation from the lower end side of the inner peripheral wall. In addition, this engagement is formed so that it can be easily released when the push button is consciously pressed strongly, so that the push button can be removed from the one-touch cap when the residual content is discharged.

  Further, the folded piece may be provided with an engaging projection that can be engaged with the top portion in the non-folded state on the outer surface. By providing the engaging protrusion in this way, the engaging protrusion hits the top part during storage, transportation, assembly work, etc. before being assembled to the aerosol container, and the push button is the inner peripheral wall of the one-touch cap. It is possible to prevent detachment from the upper end side.

  The contents may contain at least one of liquefied petroleum gas, dimethyl ether, nitrogen, carbon dioxide, and isopentane used as a propellant.

    The present invention is configured as described above, and the folded pieces are formed by providing incisions on both sides of the push button, so that the folded pieces protrude from the lower end of the push button. Thus, the folded piece can be easily formed.

    In addition, the tip of the folded piece that is folded back and inserted into the slit by more than 90 degrees is abutted against the inner surface of the outer peripheral wall, so that the folded piece is prevented from elastically returning to the non-folded state, and the top part is folded back. Even if the button is pressed, the folded state of the folded piece can be maintained. Therefore, unlike the prior art, there is no risk that the folded back of the folded piece will be released by accidentally pushing the push button too deeply, and the residual contents can be discharged reliably.

  In addition, as described above, the top part of the one-touch cap fixed to the aerosol container is abutted against the outer surface of the folded piece to suppress the upward movement of the push button. There is no need to provide a joint, and it is easy to manufacture and an inexpensive product can be obtained. In addition, even when the aerosol container is subjected to vibration or impact, and the position where the top of the slit abuts against the folded piece is slightly shifted, the folded piece folded back more than 90 degrees should maintain the folded state stably. Therefore, it becomes possible to carry out smoothly without interrupting the discharge operation of the residual contents.
